STRAW-CUTTER.

SPECIFICATION forming part ef Lettere Patent Ne. 257,388, dated May 2,Issa.

Application tiled December 22, 188i. (No model.)

To all whom it may concern:

Be it known that I, CARL ROEHL, of Lockport, in the county of Niagaraand State of NewYork, have invented a new and useful Improvement inStraw-Cutters, ot which the following is a specification.

' This invention relates more particularly to that class ofstraw-cutters in which the knife moves in a vertical plane; and it hasfor its object to improve theoperation of the cutting and feedmechanism.

My invention consists of the peculiar construction of the cutting andfeed mechanism and of the means whereby the feed mechanism is connectedwith the cutting mechanism, as will be hereinafter fully set forth.

In thev accompanying drawings, consisting of two sheets, Figure l is alongitudinal section, and Fig. 2 a fragmentary side elevation, of myimproved straw cutter. Fig. 3 is a cross-section in line as w, Fig. 1;Fig. 4L is a front elevation of the machine; Fig. 5 is a cross-section,on an enlarged scale, of' the adjustable plate, whereby the length offeed is regulated. Fig. 6 is an enlarged vertical sec-V tion in line az, Fig. 4. Fig. 7 is a. cross-section in line w w, Fig. 1.

Like letters of reference refer to like parts in the several figures.

A represents the stationary frame of the machine, and A the open box ortrough in which the straw, hay, or' other substances to be cut isplaced.

b represents the knife, which is attached to a cast-frame,B,constructedwith a downward- The latter is attached with its lower end to atransverse arm, C, which is pivoted to a support, c, on the oppositeside of the machine, the support c being attached to the cross-sill A2.

D represents the actuating hand-lever, which is pivoted at d to the postA3, and connected near its opposite end by a rod, d', with the arm C ator near the point at which the knifearm B is attached to the transversearm C.

The knife-frame B is guided betweenthe vertical bars e of a frame, E,which slides vertically between the posts A3 A4 A5 A6 at the head of themachine. The frame E is preferl" ably provided with rollers c', betweenwhich `5o the end of the knife-frame B is guide-d. The frame E isattached to the cross-arm C by a connecting-rod, f, which is locatedbetween the front posts ot' the main frame. The arm B of the knifefollowsthe movement ofthe end of the arm C and the frame E receives ashorter reciprocating motion, as it is connected with the arm C, nearerits fulcrum. By this means the knife is pushed forward in the directionof its cutting-edge between the rollers e e at the same time that it iselevated and drawn back as it is lowered, whereby a drawing-cut isproduced.-

g represents acast rectangular frame, which surrounds the throat ormouth of the trough A', and g is a metallic crossbar, which is securedto the front posts of the machine, and extends across the machine inlinewith the lower horizontal bar of the frame g, a slot, g2, being formedbetween the frame g and the bar g', through which the knife works. Thebar g and the lower part of the frame g support the material to be cuton both sides of the knife and enable the latter to produce asharp cleancut.

h represents an inclined board, upon which the cut material falls, and ha vertical board, which forms a continuation of the board h and preventsthe cut material from falling rearward under the machine. Q

I represents an adjustable plate, which is attached to the inner side ofthe actuating-lever D, and which serves to limit the forward movement ofthe straw or other material caused by the feed mechanism. The plate I isattached to the lever D by means of sleeves i, which extend through thelever, and which are adjustably held therein by set-screws ft. Thesleeves are secured to the plate I by bolts iz. When the lever D israised the plate I assumes aposition opposite the mouth of the troughA', and the straw or other material is pushed against the plate I by thefeed mechanism.

K is a movable plate, which is arranged in the trough A', and whichserves to hold the 95 straw or other material down against the bottomofthe trough. The plate K is attached to a cross-piece, lc, byr springs7c', which permit the plate to yield.

L represents the cross-head of the feed mechanism, provided on its upperside with .pins or prongs I, which project upwardly into the trough A'through an opening, Z2, which extends across the bottom of the trough.The stones, earth, and similar matter contained in the straw and othermaterial fall through this opening, and are thereby prevented from injuring the knife. The cross-head L is attached to the forward end of alever, M, whose rear end is guided in an opening, m. The crossheadcarries at each end a stud or pin, prefer` ably provided with arollcr,n, which engages in a'groove, u', having approximately the form ot' anO, whereby the cross-head receives first a risin-gm-otion, then aforward motion, then a falling motion, andthen a rearwardr motion. The"grooves a' are formed in cast-platesN, whichiare secured to the sides ofthe trough A';` The arm M is actuated from the frame E byfa lever, P,which is pivoted at p to the rear end'of themai-nzframc and connectedwith thearnr M by a forwardly-inclined rod, p'. The-front end ofthellever'P engages in aeasty socket, q,which is attached to the rearsideof theifr'ame E at the pointwhere the connectingrod'fis attached tothe frame'E,;so that the same bolt q serves to connect both theconnecting-rod j' and the socket q to the frame E.

r representsaspi-ral or other suitable spring, which connects the arm Mwith the rear part of themain frame, and tends to draw the armMbackward.

s represents a curved spring, which. is secured to the under side of thetroughA', over thea-rm M, and which engages against ashoulvtheerossheaa-L and the ma M, to which it is attached, forward, therebycausing the rollers of the cross-head to pass over the ridge n2, betweenthe two vertical portions of each groove. As the lever P descends thecross-head L descends also, and its rollers move downward in thel frontportionsof the grooves n,and are returned to their rearward position bythe reaction of the spring i". In the highest position of the cross-headthe spring s is straightened and-bears against the shoulder s' of thearm M, and pushes the latter forward and compels the rollers of thecross-head L to enter the front portions of the grooves n'. In thismanner a four-part feed motion is imparted to Vthe cross-head L, whichthereby imparts an intermittent forward motion to the straw or othermaterial in the trough A'..

I claim as my invention- 1. In a straw-cutter, the combination',` withthe knife b, of the frame B, sliding at oneend in the reciprocatingframe E, and connected at the other end with the swinging arm1 G,wherebya drawin g-cut isim parted to the knife, substantially assetforth.

2. The combination, with `a trough A', of the cutterb, frame B,provided'vwith arm B', cross-arm (l, reciprocating frame E, in which theknife-frame slides, and connectingfrodf, whereby the frame E isconnected to the arm C, substantially as set forth.

3. The combination, with the trough A', of the cross-head L, providedlwith-studs yorrollers n, arm M, having shoulders', grooved plates N, aspring, r, tending to draw the arm M backward, and a spring, s, wherebythe rearward movement of the arm M is prevented whenl in its highestposition, substantially as setfo'rth.-

4. The combination, with the arm C, linkf, and reciprocating frame E,.ofthe cross-head L, arm M, springs r s, lever P, and yconnecting-rod p',all arranged to operate substantially as set forth.
